I have all of the optional dependancies installed except Button Hole.
Titan can be found here:

myAddOns is here:
http://ui.worldofwar.net/ui.php?id=222
and OutfitDisplayFrame is included in the Fishing Buddy package available here:
http://ui.worldofwar.net/ui.php?id=1095 (scroll down to the DevZone section).
I haven't tried 1.0.200.4 yet (downloading as I type). I'll install this version and see if it works.
EDIT: Still no joy with 1.0.200.4. WoW UI Des keeps freezing at the FishingOutfitFrame.xml file on load. Removing FishingBuddy or OutfitDisplayFrame from the AddOns folder fixes it.
